Science In Your Garden
Category: Science
Tags: science for kids garden earth science life science

If you’re looking for some hands-on activities to study earth and life science, head out to a garden. It’s a living lab that affords all kinds of opportunities to observe science concepts in the natural world, such as:


  • interdependence in an environment

  • life cycles and changes

  • adaptations and biodiversity

  • human impact on the environment.

While in the field, kids get a chance to be the scientists by asking questions, making observations, and coming up with explanations for what they see based on evidence. They can define problems they may encounter in a garden (eg. a plant-damaging pest), and gather additional information to brainstorm solutions.

For an idea of the kinds of investigations that can be done in a garden, visit LifeLab, a Santa Cruz-based non-profit organization that hosts field trips and summer camps at their garden classroom. Or go online to download their free garden exploration units for grades 1 - 4. Each unit - Pondering Plants, Soil Stories, Garden Pollinators, and Garden Habitats - includes six lessons.

Additional free resources available at the LifeLab site:


Here are some more ideas from KidsGardening, like creating a biosphere in a bottle.
